Definitions

  • the present invention relates to a sandwich scraper blade for the snow blade of a snow plow, which is provided at the top with a steel mounting neck, on which a rubber body is vulcanized with at least one embedded hard material body.
  • a sandwich scraper is known from DE 34 04 030 C1.
  • the hard material bodies of the aforementioned sandwich scraper are rod-shaped or plate-shaped molded bodies, which preferably consist of sintered or cast corundum. Such sandwich scrapers have proven to be excellent.
  • a scraper blade for a construction machine or snow plow shield which has a steel scraper bar on the underside of which a plurality of steel segments are screwed.
  • the steel segments are preferably forged from a tool steel having a higher wear resistance than the steel of the scraper. In the area of the wear surface facing the ground, V-shaped cemented carbide cores are inserted into the steel segments.
  • the present invention has for its object to provide a scraper, which is exposed to low wear, has a correspondingly long service life, does not damage the road surface and is also suitable for blackout of the road.
  • the hard metal core must be firmly anchored in the steel shell. This can be non-positively - such as by shrinking - and / or cohesively - such as by soldering - done.
  • a further advantage of the use according to the invention of a steel jacket is better heat distribution.
  • the rubbing of the carbide core on the asphalt produces a lot of heat, which is transferred from the steel to the rubber via large surface areas.
  • local overheating of the rubber is avoided, resulting in significantly less wear than when directly embedding hard metal cores in the rubber.
  • Carbides are comparatively expensive materials.
  • the cost of the sandwich scraper can be significantly reduced by using carbide cores made from recycled carbide. This is processed waste material from worn tools of machining.
  • the steel shell or the hard metal core is formed as a rod-shaped or plate-shaped molded body, which extends at best over the entire wear height of the sandwich scraper.
  • Carbide core and steel jacket should together occupy a high surface area of the wear surface of the rubber body. Their area share should amount to at least 20%.
  • the sandwich scraper bar is particularly stiff and removes even stuck and verharschten snow residue from the asphalt surface.
  • the rubber body of the sandwich scraper is covered from both sides with steel plates, it is recommended for reasons of weight, to dispense with a separate mounting neck and instead to use at least one of the two steel plates at the same time as a mounting neck.
  • the wear surface is composed in cross section of a seven-layer sandwich.
  • the individual layers are - contrary to the direction of advance of the plow blade - the steel of the rear steel plate, the rubber of the rubber body, the steel of the steel shell, the hard metal of the hard metal core, the steel of the steel shell, the rubber of the rubber body and the steel of the front steel plate.
  • the sandwich is therefore symmetrical and effectively protects the brittle core against impacts.
  • Fig. 1 sandwich scraper in cross section
  • Fig. 2 sandwich scraper with steel plates on both sides in cross section Q
  • Fig. 3 Sandwich scraper with steel plates on both sides in front view.
  • the sandwich scraper 0 shows a first embodiment of the sandwich scraper strip 0 according to the invention in cross-section, ie substantially transversely to the direction of travel, or to the feed direction V.
  • the sandwich scraper 0 comprises a steel attachment collar 1, via which it is attached to a not shown Dozer blade of a snow plow, also not shown, can be attached.
  • the attachment is usually by Screw connections or by means of clamping claws; Further joining techniques are conceivable.
  • the sandwich scraper 0 comprises a rubber body 4, which is vulcanized to the mounting neck 1. Rubber has proven itself as a material, but it is nevertheless possible to substitute it with a suitable plastic.
  • a steel shell 5 is embedded, which surrounds one or more hard metal cores 6.
  • Both the steel jacket 5 and the hard metal cores 6 can extend continuously over the entire length of the sandwich scraper bar 0. Preferably, however, they are interrupted in sections.
  • the hard metal cores 6 each extend at least over the wear height h of the scraper blade 0.
  • Steel jacket 5 and hard metal core 6 together make up at least one fifth of the wear surface 7 of the rubber body 4.
  • the hard metal cores 6 are preferably made of tungsten carbide, titanium carbide or titanium nitride. These materials can also be used as recyclate.
  • the hard metal cores 6 is either shrunk into the steel shell 5 and / or soldered to it.
  • the steel jacket 5 is, however, vulcanized into the rubber body 4.
  • the sandwich scraper 0 is formed by a five-ply, symmetrical sandwich.

It comprises two steel plates 2, 3 which cover the rubber body 4 at its front side and at its rear side. The front steel plate 2 is largely flat, the rear steel plate 3 is cranked. Both steel plates 2,3 are connected by vulcanization with the rubber body 4 and also serve as a fastening neck 1. For this reason, they have in the upper part of holes 8, through which bolts, not shown, are inserted for attachment to the dozer blade.

Abstract

L'invention concerne une latte de déblayage de type sandwich (0) pour la lame de déblayage d'un chasse-neige, munie, en haut, d'un col de fixation (1) en acier, sur lequel un corps en caoutchouc (4) présentant au moins un corps en matière dur inséré est prévulcanisé. Il est prévu, selon l'invention, de concevoir le corps en matière dure sous forme de noyau en métal dur (6) entouré d'une enveloppe en acier (5). Cette mesure confère une durée de vie étonnamment élevée à la latte de déblayage de type sandwich (0).
